Calling operator new freezes psp!

[theHobbit]

Hi i'm working on porting the Game_Music_Emu library, but i'm having some problems. It seems everytime the operator new is called the psp just frezees. Well it works with simple variables like chars or ints, but when I use it with a c++ class it freezes.

For example:
int *intr_ptr = new int; OK
Music_Emu *emu = new Nsf_Emu; Don't work

Where Nsf_Emu is a class. Any help?

EDIT:
Problem Solved, thanks to blargg, It was something to do with the library endianes.

Is it a class which allocates a lot of memory in its constructor? (Or one which contains a large array?)

More debugging needed unfortunately...
